5, strand theory

"http://www.motionmountain.net/research.html"

strands have no endings, thus there is actually only one ring tangled into itself
strands have no restriction other than themselves
	a strand is everywhere at all times, unless when other strands restrict it
note that strand restriction is a collective process,
	ie it's determined by the whole structure of a strand configuration

collective restrictions lead to a number of different rational (ie unknotted) tangles,
	called elementary tangles, which are made of 3 or less strands

a photon is a twist on a strand, it moves (on average) at the speed of light
the twist turns around the strand, and the frequency of this rotation is the photon's frequency

massive elementary particles are tangles of two or three strands
in free space they move with a constant velocity (on average) less than the speed of light

charged particles have chiral tangles
due to collective restrictions, chiral tangles can absorb or emit photons,
	and as a result change their (average) velocity

note that when a photon is absorbed, its original strand will be unrestricted,
	and thus disappears into the border of space
this is also what happens when emitting photons
when a photon appears on a strand of a particle, and move away from it,
	the strand between the particle and the photon will be unrestricted

some tangles are unstable and decay into stable ones
mirror tangles neutralize each other's restrictions, and allow the cores to be untangled,
	which results in high frequency photons

virtual particles are temporary tangles, ie tangles which annihilate after a short time

mass is the amount of inter'tangledness, and thus it determines the inertial difficulty to move the tangle,
	as well as the curvature of spacetime
